The computer has added on more dimensions such as speed, accuracy and increased volume of data that permit the consideration of more alternatives in decision-making process. The lifespan of most product has continued getting shorter and shorter and therefore the challenge to the manager is to design product that will take a longer shelf life and in order to do this, the manager must be able to keep abreast of the factors that influences the organization product and services thus, management information system come in handy in supporting the process.

Management information services helps manager to access relevant, accurate, up-to-date information which is the more sure way of making accurate decisions. It also helps in automation and incorporation of research and management science techniques into the overall management information system for example probability theory. The management information services are capable of taking advantage of the computational ability of the company like processing, storage capacity among others
Management has been define in process or activities that describe what managers do in the operation for their organization plan, organize, initiate and control operations.Data must be distinguished from information and the distinction is clear and important for present purpose. The system concept of MIS is, therefore one of optimizing the output of the organization by connecting the operating subsystems through the medium of information exchange. Though there are a number of definitions all of them converge on a single point, i.e. the MIS is a system that support the decision-making function of the organization.
